dr. sch kr schaffner, good morn >> good morning, everyone. i think we'll see that all over the country, people are sneezing, coughing, and having fever. i think we'll also hear from the cdc a midterm report on how effective the vaccine is. i anticipate that it will be same ol', same ol'. it's a good vaccine but not a perfect vaccine. i anticipate it's able to prevent, over, 60% to 70% of all infections. those it doesn't prevent it often, however, makes milder. that's harder to measure. if you haven't had pneumonia, you haven't been hospitalized, and, hello, you haven't died, that's also an effect of the flu vaccine. >> doctor, i actually went into a pharmacy last night and they said they had only two doses left. is this a concern about the shortage of doses left? >> it's bad news and good news.
